Depiction of laser-induced electron diffraction imaging of a molecular bond break-up in acetylene.

The particle size of the fat droplets present in dairy and other food emulsions is important in defining properties such as flavor release, mouth feel and emulsion stability. Thus, a knowledge of the particle size is critical in defining the functionality and taste of different food emulsion products. Here we show how laser diffraction can be used to measure and understand the changes in size that occur during production and storage of dairy products. This in turn can lead to a better understanding of how product formulation and performance are linked.

Nanoparticle Tracking Analysis (NTA) has found use in a variety of investigations researching the toxicity and environmental impact of nanoparticles. Here we discuss various publications in which NTA has been used to measure particle size and concentration of nanomaterials in waste water.

A Chinese research group have discovered potentially dangerous levels of lead in lipsticks

The world is in serious trouble when “Photoshop” is added as a major skill on the curricula vitae of scientists.

What is the chemical nature of thought? What is memory? Why, over 2000 years since Aristotle first asked such questions, are we still searching?

Don your purple nitrile gloves and grab a swab or two, as we delve into the realities of crime scene investigation.

Triple detection GPC/SEC combines measurements from multiple detectors to offer not only increased amounts of data, but also increased amounts of information, which is made available by the combination of different detectors (and unobtainable using individual detectors separately). The theory of triple detection GPC/SEC is described here.

The analytical world in general has yet to appreciate the power of FTIR spectroscopic imaging for process analysis. Here’s why it should be in your toolkit.
